To hold the web taut on the platen, 11 there` is provided a spring-actuated felt-lined-clarnping bar, 33, which is held by vthe springs,

'all the c Si, 34, against lthe web as it passesa'round the t'ront edge vot'gth'e carrier tablet, l0,

pressing it against that edge with a braking effect, requiring considerable stress to be exerted in winding the web onto the roll, 23;

and 4to hold vit taut when the operator stops winding to halt the web on the platen for being l'lunched, there is provided a loclung 'device toengage the hand wheel, 23, consisting of a friction brake spring bar, 40, carried on the bracket, ".20, andbearing on the hainlwheel. 23". A hand lever, 3,8, is fulcrlinied at 3S ontliebracket. :20, which niay be rocked from iull linel position shown 'in Fig. :2 to dotted line position in that tig` ure to press the spring brake oit the wheel.

'To `admit the end ot' the. web between the brake rod. 33, and the edge of the carrier tablet. gli), the brake bar is. held away from lthe said edge by a cani, 35, carried by, a release latch, pivot'ed onithe side edge of vthe carrier tablet, 10, and adapted to be swung down forward to rotate the cam in engageinent with a pin, 35", which Vprojects from the end oi the bar. 33. asse'en in Fig; 4. 1T. is a stripper consisting of a bar which extends across the web quitevel'os'e to the lipto strip 'the web from thepunch when the latter is withdrawn after its lcuttingi action. lt is convenient to have this stripper reniovable so as to avoid the necessity of introducc ing the end 'of the web under the stripper at starting; and to accommodate its removal and replaceinent. the stripper bar has at its per surface of the 'platenand near the punch f ends transverse Steins, 1T, which enter s'ook- I rediiced neck of the stein (see Fig; 5 and Eig. Q) and swing around horizontally oja the` 'other steinto clear the path for the' web. tenholder. 12. is secured in place ji-ier tablet, 10, by being clamped 'against the stop bar, 13, at the right lhand side by nieans ot' a clainp yscrew, 15, set throtigh a block, 19a, secured rernovably yto the carrien'or to the opposite block, 13, the block, 19a, being used with .a short platen, such as. is adapted for the narrow web re)- 'qnired for stenciling on only one `'margin of the music roll, and being refrno'vedto permit the use of the set screw in said opposite block, 13,-when a long platen needed for a wide stencil web is required for ste/nciling both margins ot the music roll.

T9 .afford a delnite step for the movement of the platen carrier cross-wise of the length of the web, so as to produce the stencil cuttings with a definite and uniform margin at the side of the web` and thereby- For operating the hammer there 1s provided produce the stencilings on the music roll with like definite and uniform margin, there is mounted iii the main support bed, l, a margin stop plate, 4T, having holes, 48, in two rows, staggeredso that utilizing the two rows, a stop p in may be located at any one of a succession ot' positions at intervals not greater than the diameter ot' the holes, 48.

say, one-sixteenth of an inch. A stoppin,

49', being inserted in one of these holes, determines the position of the right-hand edge of the carrier 10. For more exact positioning of the carrier, and to compensate for wear of the stop pin or of the abutting edge ot' the carrier. the stop plate, 47, has a short range of longitudinal movement along its seat in the bed, and is stopped atl its riglit-liaiid end by an adjusting screw, 45, set into theedge of the bed which is provided with an embedded nut., 46, to hold the screw. a lock-mitT 46a. being employed to secure theadjustment. As illustrated, this stop plate, 4T, is secured by screws on the top of a wooden block, 47a, which is of sufiicient thickness and width to obtain a safe and durable slide-bearing in the bed, 1, and is provided at the outer end with a metal sheath plate, 47b. to receive the thrust of the adjusting screw.

The punch carrier is a wheel. 50, turning `on a vertical axle, 51, which is inthe form of a headed bolt screwed into a boss. 5 3, positioned about midway in the length ot' an arch or bow or U-shaped arm, 54. which is pivoted at one end to a bracket on the main 'A support, and strides the platen and roll Vcarrier, 10. In this wheel` 50, in a circle about its axis, there are mounted for reciprocation parallel to said axis `a multiplicityY of punches, G0. each carried by a radially-extending fiat spring arm, Gl', secured at its inner end to the hub. 50a, of the punch carrier. The punches are held by their spring arms, so as to normally have` their lower cutting ends raised a little above :the web on the platen. The hammer` 70, for driving the punches against the platen is carried by the spring arin. 71, preferably as shown con.-

sistiiig ot' a several-leaf spring secured tcl the bow or U-shaped arm, 54. a bracket, 5T, mounted onthe forward side of said arm being provided tor so attaching the hammer spring arm. In order to obtain sufficient. length of the spring arm, the bracket to which said'arm is attached is shown at a. considerable distance from the fore-andlaft vertical plane of the platen ott' toward the right hand end of the machine. The hammei' head is mounted on a spring arm. and said spring arm is mounted on the U-shaped arm, 54, in such position that the head of the hammer normally stands a little above the vhead of the punch when the punch stands at-its normal position with its lower end as described, raised a little above the platen.

a double eccentric cam, comprising two eccentric members. 80.780, .each having a radial shoulder, a, said two shoulders b eing in the same diametric ilane through the y axis of the cam shaft,8l. aid shaft is jour-` naled in bearing brackets, 82, 82, extended `from the arm, s3-l, and the cam is positioned so that its eccentrics described engage under the springliaminer arin. flexingit upward `as the cam is revolved and lifting it to the position shown -in said Fig. 4, atwhich said spring 'arm runs off the veccentric engaged with the cani, and descends along the radial j edge or shoulder, said spring arm being. put

Vunder extreme tension in the flexing to which it is subjectedsby .the'lifting action .of the cam, so that in its reaction` descendingas described along said radial edge of vthe cam, it causesr the hammer to deliver` an `effective blow to the punch. Both the punch and the hammer react 'after the blow to the normal position, the punch outof 'contact with the web .and-the hammer out of contact with the punch; but` the reaction` of the" 'hammer dueto lthe stiffness of its spring arm. and the,extreme flexure to which it `has been subjected, will tend to cause it to carry it much beyond its normal position, giving repeated blows to the punch.` To

rprevenhtliis,result. following thehainmer lfork or clasp positioned in the path of the descending hammer; and the ,lower endot the hammer ismade similarly truste-conical inform to enterl said clasp as the hannner descends. spreading it and becoming t'i'ictionall;7 engaged with it to such a degree as to materially' retard the recoil ot' the hain- ,iner and prevent its recoil'froin ,carrying it materially beyond its normal position, thus preventingthe repeated vibration back and forth and repeated strokes `upon the punch which wouldotherwise` occur. j

Iii order to position the punches accurately below the hammer and abovevthev platen lfor cutting the stencil openings at the right point in the web, the periphery 'of the wheel which constitutes the punch carrier vhas a notch, 5T, opposite the position of each punch, and a spring dog, 58, depending from the arm. 54, is mounted to engage these ynotches respectively atthe position of the `wheel at which the respective vpunches aie properly located for receivingrthe hammer stroke and cutting the stencil; i 'The notches and the engaging head of the spring dog are so corielatively shaped that the dog is disengaged by moderate force applied to turning the wheel or punch carrier. For convenience, the rim of the punch carrier wheel, 50, has its upper edge provided with a beveled zone, 59, on which are marked opposite the respective punches, the letters and characters which the punches are adapted to cut in the stencil web. i

To facilitate introducing the stencil web across the platen and the commencement ot' the operation and in some cases its removal which will become necessary before it has -been completely unwound from the roll 19,

and wound onto the 1011,23, the U-shaped arm, 51, which carries the punch carrier is pivoted as stated at one end, and adapted to be swung up and over` from the operative position of the punch carrier to a position shown in dotted line in Fig. 1, where it rests upon a support provided for holding it in this position, leaving the platen carrier and all parts thereon unobstructed for the placing of the stencil web in position. For thus pivoting the arm, 54, and at the same time providing for a limited amount of vertical adjustment which may be desirable to accurately position the punches with respect to the mateur-compensating for the vari-ation and wear of the platen, and of punches as they may be reduced by grinding fromtime to time,-there is provided a bracket member consisting of a. board, 5, having rabbetted edges engaged with reciprocally-rabbetted side bars, 6,' 6, secured on the right -hand end of the main support frame structure, as most clearly seen in Fig. 7: said board having the oblique bracing bar, 5", secured to it near the i lower end, and extending thence upwardly and off to the right, as seen invFig. 1, and provided with a tie bar. 5c, connecting it at its upper end back to the board, 5. Pivot lugs, 5, are secured'to the upper end of the board, 5, for affording pivotal connectionof the lower right hand end of the U-shaped arm, 54, which is forked at that end, as seen in Fig. 2, the fork arms, 54X, being pivoted respectievely to the two pivot lugs, 5, secured as shown in Fig. 6, to the upper end of the board, 5. Upon the frame structure ot the `main support, as upon the tie bar, 3b, which connects the legs, 2, 2. at the right hand side, there is mounted a supporting and adjusting screw, 5d, said screw being set through a threaded sleeve or stud. 5e. which is secured to. said bar, 3"; andv said screw protruding through the upper end of said threaded sleeve or nut aords lodgment for the lower end of the board, 5, which is provided with a wearing plate, 5, to receive the thrust of the screw. The screw has preferably a wing head for operating by. hand, andf is provided with a wing nut, 5m, serving as a jam nut to hold it securely in adjusted positionl The opposite end of the U-shap'ed frame o r bar, .5-1, is stepped on an adjusting screw, 8, set up through the bed, 1, on the under side of which there is mounted a tixed nut, 8, for said adjusting screw.

The step-bystep movement ot' the platen and roll carrier for moving the web one letter space at a time for cutting the successive letters or characters in a line. is performed by means of a spring-actuated pawl, 90, engaging the ratchet-tootlied feed bar, 91, which is secured at 92, to the platen carrier, 10, and extends thence to the left along the top ot' the bed, 1, having its lower edge provided with the ratchet teeth. The bed, 1` is apertured under said ratchet toothed bar to admit the pawl, 90, and the lever, 93, by which it is carried` said vlever being pivoted to the bed, 1. within the aperture, as shown at 9-1, and extending down for connection at its lower end with alink, 95, the right hand end of which is connected with the upstanding arm, 96, of the bell crank lever, whose arm. 9T, is connected by a link, 98, with a pedal, 99, fulcrumed on a bracket block,.10(), mounted on the floor on which the machine stands, in a position to be conveniently within reach of the foot of the operator while standiiig-in front of the machine to manipulate the punch carrier for putting the proper punches into operating position. lt will be understood that the pawl and ratchet ste-p feed device is arranged to feed the platen carrier from right to leftr-that is, in direction for cutting successive characters in a lineto be read from left. to right.l The pawl is mounted on the operating lever 93, by a pivot, 93a, about .which it is pressed by'the spring, 93", for the. encounter of its lower edge with the stop pin, 93, and at this position of the pawl on the lever when the lever, 93. isin full line position shown in Fig. 1, the pawl is out of engagement with the teeth of the feed bar, 91; but, moving rigidly with the lever, 93, as it is rocked about its fulcrum, 94. to the dotted line position shown in said Fig., 8. the head ot the pawl moving in an.

arc about said -fulcrun., 9-1, advances upwardly to engagement with the ratchet bar, and upon further movement of the lever in the same direction, the lever rocking about y, its fulcrum. draws the pawl. now engaged with theiatchet bar, to the left, actuating the bar in the same direction for the step feed movement ot` the'platen carrier which is desired. The pawl being, normally disengaged from t-lie ratchet bar, the operator may at any time move the platen carrier in either direction,to the right for restoring it to the starting position for a new line, or to the left for producing an interval between successive characters in the same'line, or for passing to the opposite side of the stencil for cutting characters upon said opposite marginal area. The ratchet bar, 91, is housed and held against displacement by thepawl action' on it bya# housing bracket, 91, mounted on top of thebed, l..

This housing limits the movement of the platen carrier to the left; and to check its movement under the feeding action of the pawl there. is provided a spring brake, 91", secured to one wall of a channel formed between two blocks, 91e, 91C, between which the ratchet bar slides, and holding the pressed against the opposite a platen on said carrier; a pair of rolls from and onto which vrespectively a stencil web may be wound mounted on the platen carrier at oppositev sides of the platen; and guide means for the stencil web at opposite sides Vof the platen, the platen being elevated above. the plane of said guides.v
